Return true if 'source' exists and is more recently modified than
    'target', or if 'source' exists and 'target' doesn't.

Return false if both exist and 'target' is the same age or younger
    than 'source'. Raise DistutilsFileError if 'source' does not exist.

Note that this test is not very accurate: files created in the same second
    will have the same "age".

    listed in 'sources'.

In other words, if 'target' exists and is newer
    than every file in 'sources', return false; otherwise return true.
    'missing' controls what we do when a source file is missing; the
    default ("error") is to blow up with an OSError from inside 'stat()';
    if it is "ignore", we silently drop any missing source files; if it is
    "newer", any missing source files make us assume that 'target' is
    out-of-date (this is handy in "dry-run" mode: it'll make you pretend to
    carry out commands that wouldn't work because inputs are missing, but
    that doesn't matter because you're not actually going to run the
    commands).
